问题:

对波斯人的入侵,雅典使节向斯巴达人保证说,他们绝不会背叛希腊人,因为他们有着共同的血缘和语言、共同的祭坛……在城邦危机时代,“泛希腊主义"的思想观念日益强烈。从表面上看,这种文化认同感的形成似有助于希腊世界的政治统一,但是希腊人的文化认同感植根于更深刻的层次。在他们看来,他们与非希腊人的本质区别正在于他们是生活在城邦里的,而非希腊人不是;他们作为“城邦动物"的属性才构成希腊文化一致性的原初基点,其他的表征均衍生于此。该材料()

A.说明了希腊城邦之间矛盾重重

B.体现了希腊人反抗外来侵略的坚强决心

C.论述了希腊没有形成统一国家的原因

D.解读了希腊民主政治的内涵

用自由落体法进行“验证机械能守恒定律”的实验

(1)实验完毕后选出一条纸带如图所示,其中O点为电磁打点计时器打下的第一个点,A、B、C为三个计数点,打点计时器通以50Hz的交流电。用刻度尺测得OA=12.41cm,OB=18.60cm,OC=27.21cm,在计数点A和B、B和C之间还各有一个点,重物的质量为1.00kg,取g=9.80m/s2。甲同学根据以上数据算出:当打点计时器打到B点时重物的重力势能比开始下落时减少了________J;此时重物的动能比开始下落时增加了_______J。(结果均保留三位有效数字)。

实验中产生系统误差的原因是______________________                       

(2)乙同学利用他自己实验时打出的纸带,测量出了各计数点到打点计时器打下的第一个点的距离h,算出了各计数点对应的速度v,以h为横轴,以为纵轴画出了如图的图线。图线未过原点O的原因是____________________________________________。
